9 Claims. (Cl. 160-672) This invention relates to storm windows, and it particularly pertains to storm windows which are readily extensible for being readily adjustably fitted to be in stalled in place.

Storm windows now used are of complicated construction, cumbersome to handle and install, and require skilled mechanics for installing them, particularly those having a frame for the window pane or panes. Therefore, they are ordinarily permanently installed and left in place because of being too cumbersome and complicated to be removed between seasons.

Accordingly, one of the main objects of the present in-' vention is a storm window which is simple in construction and easily installed. V 'Anoth'e'r-object of the invention is a framed storm window which is light in weight and extensible.

Still another object of the invention is a storm window which can be installed and removed without skilled help.

A still further object of the invention is a storm window in which one or more windows may be arranged in parallel spaced apart planes.

Further objects, and objects relating to details of construction and economies of operation, will readily appear from the detailed description to follow. In one instance, I have accomplished the objects of my invention by the device and means set forth in the following specification. My invention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which:

Fig. l is a perspective view of a portion of a storm window partly in section, embodying the invention fitted to a conventional house window.

Fig. 2 is a cross-section on line 2-2 of Fig. 1.

Fig. 3 is a view of one common portion, with the window pane part removed, embodying the invention.

Fig. 4 is a perspective view of one of the clips for fitting the storm windows in place.

Generally described the invention comprises a rectangular open frame, with longitudinally extensible side sections to which one or more panes may be readily fitted by being stretched over the frame with its opposite sides and ends detachably secured to the frame. The fitting of the panes to the frame helps to hold the sectional sides of the frame in selected extended position.

Referring specifically to the drawings in which like numerals designate like parts, numeral 2 is a bottom sill between the side facial strips 3 of a conventional window frame in which is mounted a window sash 3 carrying a glass pane 4. Ordinarily, there are two window sashes, an upper and lower, vertically slidable in parallel planes.

An angle clip 5, with sides 6 and 7, is fastened to opposite sides and/or to the top and bottom ends of the window frame, each of the sides of the clip being provided with openings 8 therethrough. Ordinarily, about four of these clips are sufficient, two being fas- 2,804,139 Patented Aug. 27, 1957 tened to each side with one disposed near the top and the other near the bottom of the window. The openings 8 are provided in both sides of the clips so that they may be fastened either to the inside edge of the facial strip 3 or to the sash guide strip 10. A spring finger 11 is formed on the edge of side 6 of the angle strip, generally parallel to the side 7 and terminating in a beaded end 12. This finger 11 and its beaded end 12 form a receiving channel, with a constricted neck, between it and the side 7 for a channel strip 13 of rubber inserted therein with the channel 14 opening inwardly opposite to a flexible lip 15 formed on the bottom, this lip 15 being flexible enough to effect a seal between said strip 13 and the adjacent contacted portion of the window frame. This clip 5 for holding the channel strip 13 is optional, it being understood that the channel strip could be secured directly to the window frame by nails driven therethrough or with adhesive.

A rectangular frame 16 having sides composed of longitudinally extensible sections 17 and 18 is mounted in the channel strips 13. These frame side sections 17 and 18 are made of sheet metal or of moldable composition. One section 17 is formed with an intermediate portion bent into a rib 19 with spaced apart parallel walls 20 bent oppositely and outwardly into portions 21 and backwardly into terminal portions 22, thereby forming a main channel 23 in the rib 19 on one side and two subsidiary channels 24 on the opposite sides adjacent said rib.

walls 25 of therib 26 are in contact and of a width to be slidably fitted in the main channel 23 of the section 17 with the other parts 27 and 28 bent to form subsidiary channels 29 in which the bent portions forming the subsidiary channels 23 of section 17 are nested.

The parts 27 and 23 of this section 18 are of such dimensions that the edges of their free ends will be substantially flush when the frame sections are nested together, or, if desired, the free ends of the parts 28 could be slightly longer to be bent over the free edges of parts 22 of the other section 17. Such construction would permit the side sections of the frame to be assembled and disassembled only in end to end relation, and prevent lateral assembly and disassembly thereof. However, lateral assembly and disassembly is unnecessary inas much as the sections can be snugly fitted together, and, therefore, any overhanging end portions are preferably omitted, more particularly since the nested main ribs can be tightly fitted together for holding the sections in extended position, and the sections are further secured as hereinafter described.

After the frame has been fitted to the window, a flexible transparent sheet 30, such as plastic film, can be stretched across the open frame with its marginal edges 31 fitted into one of the surrounding channels of the frame and adhesively secured therein and/or by rope cords 32 press-fitted in the channel. The frame is of a construction having two surrounding channels, in different vertical planes, to permit the use of two transparent sheets 30. Either one or two of the transparent sheets can be used as desired. The press-fitted rope cords 32 further secure the side sections of the frame in any extended position to which they are adjusted.

A bracing strip 33 composed of adjustable sections 34 and 35 may be inserted between the opposite sides of the frame to reenforce them if such be found desirable. However, the frames are of suflicient rigidity, particularly when assembled, to be held in assembled position, and bracing strips are ordinarily unnecessary.

From the foregoing description, it will be apparent that the frames may be first installed and fitted in position, after which the flexible plastic sheets are applied, or

The other section 18 is similarly bent except that they 3 the flexible plastic sheets can first be fitted to the frames after which the frames are installed.

I am aware that there may be various changes in details of construction without departing from the spirit of my invention, and, therefore, I claim my invention broadly as indicated by the appended claims.

Having thus described my invention, What I claim as new and useful and desire to secure by U. S. Letters Patent, is:

1. A rectangular frame for a flexible sheet adapted to be readily detachably connected with a window frame as an assembled unit comprising longitudinally extensible side sections formed from metal strips having opposite free marginal side edges bent outwardly and backwardly to provide spaced-apart surrounding peripheral channels, an outwardly extending peripheral rib deformed from the metal strip between said channels, a flexible sheet stretched across the frame with its opposite margins extending into one of the channels, and means for wedging the margins of the flexible sheet in one of the channels.

2. The rectangular frame of claim in which the peripheral rib is formed by transversely retroverting a portion of the metal strips between the opposite marginal bent edges.

3. The combination of the rectangular frame of claim 2 and a sealing strip channeled on one edge to fit the rib of the frame and provided with a flexible lip on the edge opposite the channeled edge of said sealing strip.

4. A rectangular frame for a flexible sheet adapted to be readily detachably connected with a window frame as a nassembled unit comprising longitudinally extensible side sections formed from metal strips having an outwardly extending peripheral rib formed by bending opposite sides of the strips transversely to bring them in parallelism, and one terminal edge of the ships bent outwardly and backwardly to form a peripheral channel.

5. The combination of the frame of claim 4 and a flexible sheet spanning the frame with its marginal edges secured in the channel.

6. The rectangular frame of claim 4 having both terminal edges of the metal strips bent outwardly and backwardly to form a pair of peripheral channels.

7. The combination of the frame of claim 6 and a pair of flexible sheets spanning the frame, the marginal edges of each sheet being secured in one of the channels.

8. A rectangular frame for a flexible sheet adapted to be readily detachably connected with a window frame as an assembled unit comprising longitudinally extensible side sections, slidably interfitted, and formed from metal strips having a medial portion thereof doubled to provide an outwardly extending surrounding rib and one of their free marginal edges bent outwardly and backwardly to provide a surrounding channel.

9. The rectangular frame of claim 8 in which both of the free marginal edges of the metal strip are bent outwardly and backwardly to provide a pair of surrounding channels.
